Bug 22030 – importC: Wrong error with bad declarator

For example: --- int ); --- GCC errors with: --- error: expected identifier or ‘(’ before ‘)’ token --- But DMD errors with: --- Error: `=`, `;` or `,` expected --- There is the following line in cparse.d --- error("identifier or `(` expected"); // ) --- which is hit with code such as `int * )`, this seems to suggest that cparseDeclarator has an incomplete implementation.

A further example: --- int , int; --- When compiled with GCC: --- test.c:1: error: expected identifier or ‘(’ before ‘,’ token --- However DMD compiles with no errors. So DMD is not respecting the grammar in C11 6.7 (and in particular 6.7.6), which says that `int;` is valid (declaration-specifier without an init-declarator-list), but `int,` is not. declaration: declaration-specifiers init-declarator-list(opt); init-declarator-list: init-declarator init-declarator-list , init-declarator init-declarator: declarator declarator = initializer declarator: pointer(opt) direct-declarator direct-declarator: identifier attribute-specifier-sequence(opt) ( declarator ) array-declarator attribute-specifier-sequence(opt) function-declarator attribute-specifier-sequence(opt)
